摘要
利用基本的光学元件和光源,搭建Mach-Zehnder(M-Z)干涉仪,测量压力对空气折射率的影响和不同热源的热场分布.将传统光学实验与计算机的图像处理技术相结合,求得温度场为等密度线,并对实验现象进行了分析与研究.本实验可作为各类高校的设计性实验.
By using some basic optical components and light source, we build up the Mach-Zehnder interfer- ometer in the laboratory for measuring the impact of pressure on the refractive index of air and different source heat distribution. Combining traditional optical experiments with computer image processing technology, we obtain the temperature field, which is the lines of equal density, and the experimental phenomena is also discussed. This ex- periment can be used as a design experiment for colleges and universities.
